Brief introduction to common faults and maintenance of hydraulic press
Hydraulic press is a kind of machine with liquid as working medium. It is mainly composed of main engine, power system and hydraulic control system. It is widely used in manufacturing industry. Then, the best machine will have problems if it is used for a long time, which requires fault understanding and troubleshooting. Next, let's talk about the common faults and maintenance of hydraulic press.
Common faults and maintenance of hydraulic press first of all, common faults often occur when the lifting rod does not move; Reverse rotation of oil pump; Unstable pressure; Oil leakage; Loud noise, etc.
Secondly, to answer the maintenance, when the lifting rod does not move when the hydraulic press is working, the possible reason is that there are stolen goods or foreign matters in the high-pressure pump, or the oil seal is damaged. At this time, the maintenance method is to take out the stolen goods or foreign matters in the high-pressure pump, or replace the oil seal with a new one.
When the oil pump reverses, there may be a problem with the motor line. You can reconnect the motor line. When the pressure is unstable, the medium oil can be replaced. If there is air in the oil and pipeline, remove the air. In case of oil leakage, there are many possible reasons, such as the seal is broken, or the design and processing of the hydraulic press. The former is very simple to replace the seal, and the latter needs to contact the manufacturer. In case of large noise, the transmission system can be checked to reduce the noise caused by mechanical vibration and friction.
In fact, as a qualified hydraulic press operator, you must master the knowledge of common faults and maintenance of hydraulic press. You can constantly learn and carefully summarize in your daily work, so that the maintenance of common faults will be more accurate and in place.
